[sugar] during booting, previous stuff shows up on screen, then goes away

[Mikus Grinbergs]

G1G1.  Put on recent (one-day-old) Joyride and Update.1 builds. 
After the ring of boot dots is (circularly) drawn, I'm seeing some 
of the screen content from *earlier* in the boot sequence (e.g., 
around 'ok' time).  Then sugar finishes initializing, and goes on to 
display the "normal" Main view.
